Turbulence: Refers to how rapid and strong the water movement is. Turion: A modified bud, the leaves of which contain abundant storage reserves, by which the plant survives Winter and renews its growth in Spring.
Turbulence: Refers to how rapid and strong the water movement is. UGF: This type of filter involves a few long, plastic tubes which remain upright in the aquarium and are attached to a plate on the bottom.
Turbulence has long been the characteristic which aquarists use to describe the desired water motion for reef aquariums.
Lots of turbulence at the top of the contact column prevents the correct separation of the dry foam and skimmed water, thus decreasing its performance. The pH affects foam formation, too.
The benefit of this turbulence is far reaching - coral health should increase, detritus will remain in suspension to be filtered/skimmed (no more "dead spots"), and algae growth could very well decline.
This is unlike most venturi designs, where there is substantial turbulence as the air/water mixture leaves the venturi, but then goes into a relatively quiet fractionation column. CC units also tend to be quiescent.
They require somewhere to hide and a tank without too much turbulence but enough air obviously. They are a very beautiful fish to keep and are very graceful as fish go. There colours change with there moods and go very dark when upset.
Often, a filtration system that does not create too much water turbulence will be appropriate. The tanks of Red Oranda Goldfish should allow them plenty of hiding places. Cleaning should be accomplished with gradual, or partial, water change.
Water absorbs gaseous oxygen from the air at the water's surface and turbulence increases this absorption. Healthy plants give off oxygen during photosynthesis. However, photosynthesis occurs only when plants receive enough light.
they tend not to utilize parts of the tank where there's a lot of turbulence. It was quite a trick to have 2 power filters, and one powerhead outputting a total of 2500 L/h without making a harsh current in the tank.
Whisper air pump features: Patented dome shape and sound dampening chambers minimize turbulence and produce a smooth quiet stream of air + Wide footprint, ...
The water in this habitat is highly oxygenated due to the turbulence created by the rapids -- therefore the water in the aquarium should be well-aerated. Leave plenty of open swimming area, but use some large rocks.
Be sure to minimize any water surface turbulence in the aquarium. Turbulence allows the CO2 you've injected to escape into the air. Minimizing turbulence will maximize CO2 levels in the water.
At its best, Internal circulation should consist of Surge ( back and forth movement), Turbulence (random swirling movement) and Laminar flow (movement in one direction) [ see Delbeek and Sprung, The Reef Aquarium, Vol 1, page 164 ].
Depending on where they occur on natural reefs, corals may be exposed to calm waters, gentle flow, moderate turbulence, powerful surge, or crashing surf.
Purpose of project: To maximize distribution of water flow throughout tank without increasing surface turbulence.
You will need an air stone or other means to cause surface turbulence to oxygenate the water (many treatments deplete the available oxygen) and a means of mechanical filtration (sponge filters work great). I have a ten-gallon tank for this purpose.
An alternative would be to use double smaller powerheads so you can have some turbulence when the water flow crosses each other. Also, you'll have some backup here, just in case one of the powerheads dies on you.
By the second or third day you may find that the ammonia level has decreased, this is to be expected and isn't due to any remarkable super-fast bacteria growing. It's due to some of the ammonia turning into gas due to the amount of water turbulence ...
plants such as Riccia fluittans to screen out strong light and several bunches of Hygrophilia or similar plants; iron supplements for the plants, and one air driven box filter in each rear corner providing good filtration without strong turbulence.
Another method gaining popularity is the closed loop by which water is siphoned from the main tank to a pump that in turn pushes the water right back into the aquarium via multiple returns to create water turbulence.
Powerhead/filter outlets - If you place powerheads or filter outlets too close to the surface of the water, they'll create turbulence which will vent CO2.
Add a sponge filter (sponge filters will grow rotifers that the fry can eat on their surface AND they wont suck up the fry OR cause turbulence in the water).
